xxi NYMPHONIDAE PALLENIDAE 537 



Miers ( JV. /////// ////;, Bolun), an extraordinary hispid form 

 from Kerguelen, 1 is also peculiar. Pentanymphon, Hodgson 

 (1904), from the Antarctic (circumpolar), differs in no respect 

 save in the presence of a fifth pair of legs ; one species. 



The only other genus is Paranymphon, Caulleiy (1896) 

 (one species, Gulf of Gascony, West of Ireland, Greenland), in 

 which the palp is (6-) 7 -jointed, the ovigerous leg S-jninted, and 

 the auxiliary claws are absent. 



Fam. 7. Pallenidae. As in Nymphon, but appendage IT. 

 absent or rudimentary. 



Pallene, Johnston (1837): about ten species (Mediterranean, 

 North Atlantic, Arctic, Australia). P. languida, Hoek, Austral i;i, 

 lacks auxiliary claws, and is otherwise distinct ; 

 but P. novaezealandiae, G. M. Thomson, is typical. 

 Pseudopallene, Wilson (1878):" appendage III. 

 clawed ; auxiliary claws absent ; four (or more) 

 species (North Atlantic, Arctic, Antarctic). P. 

 (Phoxichilus) pygmaea, Costa (1836), and P. 

 *l>i iu>xa, (^uatref., seem to belong to this genus or 

 to Pallene. Cordylochele, G. 0. Sars (1888): closely 

 allied, but with front of cephalic segment much 



expanded and chelae remarkably swollen, includes 



J . l-'i.:. 285. Pallene 



three very smooth, elongated, northern species, to brevirostris,John- 



which Bouvier has added one from the Antarctic : 



mouth. 



Pallene laevis, Hoek, from Bass's Straits, is 



somewhat similar. Neopcdlene, Dohrn (1881): as in /W/r/e, 



hut witli a rudimentary second appendage in tin- l'rm;ile, and no 



generative aperture on tin- last leg in the m;ile. (one 



Mediterranean). ParajraWeTie, Carpenter (1892) : as in 



but without auxiliary daws, and with the two last segments of 



the trunk fwliieh in /'<///<//< are eoaleseed independent aboul
